Filter by:The objective of this clinical trial is to optimize Braindex brain tissue oxygen saturation (SctO2) measurement algorithm compared to a mixed reference value of jugular venous and systemic arterial saturation, during proven reproducible and standardized loss of brain autoregulation induced during transcatheter aortic valve replacement procedures. The main question it aims to answer is: assessing and improving the sensitivity/specificity of Braindex SctO2 measurements. Study type: single-center, prospective, interventional, open-label, exploratory clinical trial. Participant population/health status: - Patient, male or female, over 18 years of age - Patient scheduled for percutaneous femoral aortic valve replacement with aortic valve balloon deployment (Edwards Sapien valve) under simple sedation with Remifentanil (TIVA), with spontaneous ventilation. The expected outcome of this research is to optimize in vivo the algorithm for calculating the SctO2 of the BRAINDEX sensor in surgical conditions, in a context of proven low cerebral flow, on a target population. It is expected, in the long run, a better quality of detection of the loss of cerebral auto-regulation leading to a faster and optimal correction, thus potentially limiting the risk of POCD, subcortical stroke and postoperative cognitive decline.
The purpose of this project is to investigate the role of both neural inflammation and pre-existing neurodegenerative pathology in the risk and pathogenesis of post-operative cognitive dysfunction (POCD). To achieve this goal, the investigators will combine blood and cerebrospinal fluid (CSF) sampling, standardized cognitive tests, and dynamic neurophysiological markers of cortical network dysfunction in the form of event-related potentials (ERPs), to assess the link between neurodegeneration and neuroinflammation in the pathogenesis of POCD.
This is a feasibility study to determine if enough patients undergoing elective or urgent cardiac surgery, can be enrolled in a study where patients are randomized to receive high spinal anesthesia as an adjunct to general anesthesia for their cardiac surgery. The primary clinical outcome will be the incidence of post-operative delirium.
This research aims at describing the relationship between white adipose tissue inflammation and post-operative cognitive dysfunctions.The possible link between inflammatory cytokines secretions of the white adipose tissue of a surgical wound and the arising of patient's cognitive dysfunction in the post-operative course will be investigated. The hypothesis is that obese patient's inflammation of the white adipose tissue leads to cognitive dysfunction.
